Description

Subject of the invention

The invention relates to a line holder for attachment to a carrier of an aircraft structure, with a mounting portion for attachment to the carrier and a U-shaped holder portion for receiving at least one line, which is closed by a lid part via clip connection.

The field of application of the invention extends primarily to aircraft technology. In the interior of an aircraft fuselage usually run many electrical and fluidic lines, which extend on the usually made of stringers and ribs aircraft structure or below the floor of an aircraft deck and are attached to straps or the like by line holder. While a fixing portion of a wire holder is fixed to the aircraft structure, a holder portion serves to receive said wires or a wire bundle. A line holder is used primarily to attach and guide the line while fulfilling a protective function against damage.

From the DE 10 2008 041 230 A1 For example, a line holder for attaching at least one line, in particular an electrical line, to a fuselage cell structure of an aircraft emerges. The cable holder allows a torsion-free attachment of the line. In addition, a complete mechanical decoupling between the conductor holder and any stretching movements of the fuselage cell structure is achieved. The torsion-free mounting of the line is achieved by two parallel spaced-apart thigh-type racks, on which a crosspiece is snap-pushed. An attachment portion serves to attach the conductor holder to the fuselage cell structure. Since this line holder is made quite elongated and the line can be inserted only from above into the holder section, this is not suitable for all space situations within an aircraft. Thus, there are installation space situations in which a further carrier of the aircraft structure or a cover extends above the line holder, so that the insertion of the cable into the holder section is made more difficult. In extreme cases, disturbing components must first be dismantled before lines can be inserted into such a line holder.

From the DE 197 52 525 C1 goes out another line holder whose mounting portion connects laterally to a holder portion for receiving two lines. As a result, this line holder can be mounted laterally projecting on a support to adapt to confined space situations. However, here also the insertion of the lines in the holder sections from above and in addition require the attached by clip connection to the holder sections lid parts an additional pivot space for opening and closing.

The DE 102 12 484 A1 describes a conductor holder with which adjacent supply lines of different types or other elongated components set each other and / or can be fixed to a support member. It consists of a receiving part formed thereon, adapted to the respective pipe cross-section holding troughs and both sides of the holding troughs, mutually inclined clamping legs and a beatable via the receiving part circlip with it to the holding troughs of the receiving part complementary formed, also adapted to the line cross-cavities. At the two ends of the receiving part and the securing bracket latching elements are formed, which latch each other in overturning the securing bracket on the receiving part in itself. If the clamping areas defined by the clamping legs are offset from one another at the various holding troughs, a plurality of lines can be kept in a smaller space than before, without hindrances occurring in particular when inserting the lines. The DE 20 2006 011 381 U1 describes a one-piece injection-molded plastic cable holder for fixing cable and hose lines. The cable holder comprises a base plate delimited by two side walls to form an inner space for accommodating cable receiving means, wherein a cover plate which is pivotable via a film hinge is provided for closing the inner space. The cable receiving means consist of a plurality of mutually parallel, substantially U-shaped bracket portions whose inner contour is adapted in each case to form a clip connection to the outer contour of the herein to be fixed cables or hoses. The DE 10 2008 023 241 A1 relates to a cable holder for holding cables in vehicles, a method for producing a cable holder and a lining for a vehicle, comprising a cable holder. The cable holder comprises a bottom element, a cover element and a film hinge, wherein the bottom element and cover element are pivotally connected to each other by means of the film hinge and are formed such that together by pivoting the cover member about the film hinge relative to the bottom element by bottom element and cover element an exception area for a cable can be formed is.

It is the object of the present invention, a line holder for attachment to a To create carrier of an aircraft structure, which is suitable for confined space conditions of the line holder and is characterized by a simple structure and rapid assembly of a hereby to be fixed line.

Brief description of the invention

The object is achieved on the basis of a line holder according to the preamble of claim 1 in conjunction with its characterizing features. The following dependent claims reflect advantageous developments of the invention.

The invention includes the technical teaching that the attachment portion of the conduit holder is plate-like for bearing on the carrier, wherein a bottom portion of the U-shaped holder portion extends from the attachment portion substantially at right angles, and a first leg portion of the holder portion by a part of the attachment portion is formed and corresponds to an opposite second leg portion for forming an insertion opening for the conduit, which is closable via the end part applied to one of the leg portions cover part to mount the line from the side into the holder portion.

The advantage of the solution according to the invention is, in particular, that the conductor holder can be mounted flat on a support and the insertion of the conduit can take place from the side. Thus, even narrow gaps areas superimposed carrier or small distances between carriers and cladding or floor panels can be used to lay in this space lines along the aircraft structure. In particular, it requires no removal already pre-installed cladding or floor panels.

According to a preferred embodiment of the invention, the lid part should be articulated end side of the second leg region. This results in a particularly convenient installation, to which the lid part is to unfold, to insert the line via the insertion opening in the holder section. Subsequently, the lid part can be closed by folding down by clip connection.

The conductor holder according to the invention with attachment portion and holder portion may preferably consist of a plastic, which can be formed efficiently by injection molding. For this purpose, in particular a polyamide material, preferably PA66, is used. When using a plastic material for injection molding of the conduit holder according to the invention, the cover part can be articulated in a simple manner via a film hinge on the first or second leg region, so that even the hinge of the cover part can be produced by injection molding. Alternatively, it is also possible to provide a conventional hinge at this point in order to connect the cover part captive with the conductor holder.

According to the invention, the first leg region forms on the inside of the holder section a V-shaped bearing surface bevelled on both sides for guiding the line. Since the line or the cable bundle usually has a circular cross-section, can be with the V-shaped support surface in the interior of the holder portion specify an exact guidance for the course of the line. Instead or in addition, beveled V-shaped bearing surfaces for the line can also be provided on the attachment section of the line holder in the line running direction, preferably on the two opposite edges of the plate-like attachment section which comes to rest on the carrier.

The attachment of the line holder on the attachment portion on the carrier is preferably carried out via at least one separate fastening means, for example at least one screw, which passes through a respective corresponding through hole in the mounting portion and a corresponding bore in the carrier.

Preferably, the attachment portion has an integrally formed in plate plane mounting strap, in which these through holes are indeed introduced.

In order to create a space-saving arrangement, the integrally formed on the plate-like mounting portion fastening tab should extend away from the bottom portion of the holder portion outwardly, ie in the opposite direction of the insertion opening of the holder portion, so that the fastening holes inserted into the through holes not the insertion of the line in the Can hinder holder portion of the line holder.

According to another measure improving the invention, it is proposed that on one side of the plate-like fastening section a hook-shaped stop for the rectangular positioning of the line extension direction defined via the holder section is provided relative to the carrier. The stop allows the conductor holder to be placed exactly to the carrier. If pre-drilling for the attachment of the line holder are already provided in the carrier, it is possible thanks to the stop achieve a precisely aligned coincidence of the holes during assembly, which simplifies assembly. The hook-shaped stop can be formed in a simple manner directly on the attachment portion of the line holder. Thanks to the hook-shaped design of the stop surrounds the edge region of the carrier to allow attachment of the line holder to the carrier for ease of assembly.
